Urbeats

This was bonus for buying htc one s phone last year, wow last year, i already use this phone for one year haha but just remember about this bonus earphone recently 😛

Here, you can see that it is included many types of eartips.

And i found notes that state:

Because everyone’s ears are different, be sure to try out all different sizes of eartips. Only with the perfect size of eartips will you enjoy a snug fit, a sound isolating seal, and maximum sound quality

And i’m happy that i found my eartips size! :3 really good in my ears, the sound and position haha
